Profile: BLT Circuit Services Ltd. is a manufacturer of nitrogen cast solders and fluxes. We also manufacture PCB chemistries, and distribute related soldering products. We avail a range of chemicals for PCB production. Oxidizer EL is one of the chemicals we provide for de-smear application. Radikal RL is one of our copper cleaners. It is a neutral liquid concentrate. It acts as a dip pre-micro etch pattern plate cleaner, and removes film residues. We also design and manufacture effluent treatment systems either as a total package to treat all trade effluent from the printed circuit manufacturing process, or as separate units to treat waste from specific areas.
